VS 2005 DatagridView CurrentRow Index After Record Deleted?
Apr 1, 2009
i have a bound datagrid that allows users to delete & edit records within the grid using 2 buttons. delete deletes the record from the datatable. edit takes the cell values and places them in controls outside of teh datagridview for teh user to update, they then click an update button (outside datagridview) which updates the datarow
i delete a record using the dt.Rows[e.RowIndex].Delete method so that i can use the Rowstate property to do a final update on all records the problem arises when i delete a record then go to edit a record the CurrentRow index is incorrect as it still see's the deleted record.
if i delete the first record in the grid, then go to edit the next record (which is now rowIndex 0) i get an error saying unable to update deleted row contents
i then tried to use the defaultView property of the datatable when updating the row - which will update the row on screen but when i go to do the final update it see the modified row as its original deleted rowstate.

I want to delete rows in datagridview by clicking button. Have found on some sites code like:
[Code]...
But if CurrentCell is on new row and I click to delete row - it's deleting that row that is standing before current selected cell. It means that dgv.CurrentRow.IsNewRow is not showing is realy currentRow new or not! But why? Old VB version? I am using VB Professional 2008

I have an inconsistency in behaviour when I try to get the CurrentRow after a row has been selected.
If I select the first row in a DataGridView object using the mouse, the DataGridView1.SelectionChanged event fires, and DataGridView1.CurrentRow is the newly selected row (Row 0).
If I select the first row via code however ie. DataGridView1.CurrentCell = DataGridView.Rows(0).Cells(0) then the DataGridView1.SelectionChanged also fires, but CurrentRow is the old row, not the new row.
In fact CurrentRow doesn't get updated until AFTER the SelectionChanged event has fired if you force the row change in the code, but is updated BEFORE SelectionChanged if you do the row change via the mouse or keyboard.
how to check if its the first row if I've moved to the first row using CurrentCell ?

I have a datagridview that is bounded to a dataset and when i select an item to the datagridview to delete, I get the correct item. But when i sorted the datagridview to some field, it return a different item. Here is my code:
DSet.Tables("sec_company_address").Rows(sec_company_address.CurrentRow.Index).Delete()
Edit: i try this line but it brings up an error.
Dim xID As String = sec_role_module.CurrentRow.Cells("nID").Value.ToString
sDataSet.Tables(sec_role_module.Name).Rows.Find(xID).Delete()

I am able to get the index of items added to the BindingList. When I try to get the index if the deleted item I get the error Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
Here is my code
Private Sub cmdRemove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdRemove.Click
For i As Integer = 0 To _assignedSelection.SelectedCount - 1
Dim item As Jurisdiction = CType(_assignedSelection.GetSelectedRow(i), Jurisdiction)
_list.Remove(item)
Next
End Sub
Private Sub list_Change(ByVal sender As Object, ByVal e As ListChangedEventArgs) Handles _list.ListChanged

This code is intended to grab the ID of the deleted record, the user who deleted the record, and the date and time the record was deleted and insert it into a hostical table.So far, once a record is deleted, the code grabs more than one deleted record.
Protected Sub GridView1_RowDeleted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewDeletedEventArgs) Handles GridView1.RowDeleted

How will I transfer deleted record into another table instead of deleting it permanently? I think it is what we call "history"..somehow..For example I have 2 tables. 1 is Original_Record the other is Deleted_Record. If I deleted one record in Original_Record, the deleted record will be transfered into Deleted_Record table.

I am using a DataGridView, which is bound to a dataset. There is a bindingNavigator as well.
when a user deletes a row by clicking "bindingNavigatorDeleteItem" button, I am trying to get the row being deleted.
private void bindingNavigatorDeleteItem_Click(object sender, EventArgs e)
{
int crow = gridEventType.CurrentCell.RowIndex;
but it returns the newly selected row AFTER deletion of a selected row.
so, If I have two rows
0
1
2
and I delete 2
crow is 1, not 2.
Am I missing something here?
2. How do I know whether certain rows are modified in datagridview?

I have created a project that has an add a new record, edit record and a search form, that has multiple text, combo boxes and is working great.Last nite I have added a checkbox under my add new record form and i am saving the checkbox value to my database, so far so good. I would like to be able to search any record that is mark with a checkbox to show up in my search screen when I do a search: [code] The problem that i am having is that now that I have added the code to my project to search for the checkbox field in the search screen and if I leave everything blank and click on the the search button I get no record found. I expected to see all that data, since I have nothing selected. Now if I click my checkbox, as soon as I click on my search button I see that two records that I have added for my test.

I am working in VB 2008 and I have set up a datagridview to display rows of data which can then be selected. When I select the first row I get the error: Index was out of range. Must be non-negative and less than the size of the collection. When I select any other row the program executes as it should. From what I have learned so far is that the DataGridView has an index of -1 and that it counts the header row as part of the index which is the -1.When I select the first row through either DataGridView1_RowHeaderMouseClick or DataGridView1_CellContentClick the index is 0 for the first record. If the index is 0 I think it would fire off, but I have no idea what is happening behind the scenes. I can check the index, so when it is 0 and the code attempts to access the row, that is when I get the message.On an index number of 1 and up the code executes fine.So, is there a way to re-index the DataGridView, or is there a work around/fix for this issue?

I want to display the index number of the selected record in a listview box as it is clicked by the user. I can do it with multiselect set to false and the following call.
Private
Sub ListView1_SelectedIndexChanged(ByVal
sender As System.Object,
ByVal e
As System.EventArgs)
Handles ListView1.SelectedIndexChanged
[Code]...
This works fine except for one thing! after I click OK to the msgbox prompt, the record highlights normally and I click on the next record, and I get an Argument out of range exception error message, where I expected to just get another message with the next record number.

I keep getting the error message "Index out of range exception" when I run the following code.
XX
GN3 = (Loops * 5)
For a = 1 To Loops
For b = 1 To GN3
R1 = Seeds1(Counter1)
Randomize()
R2 = CInt(Int((56 * Rnd(R1)) + 1))
Counter1 += 1
MessageBox.Show(R1 & " " & Counter1 & " " & b & " " & GN3)
Next b
Next a
The message box conforms that the last entry in the array has been reached. And that Counter1 and b both start at 1 and go to 2845. And that GN3 is also 2845 all of the time.

How I can find the index for the listview on a listview click event to something like this:
Private Sub listView1_Click(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs)
MessageBox.Show(listView1.Items(e.Index).SubItems(1).Text)
End Sub
I don't want to use for each integer in the listview as i would keep getting the loops which I would hate to use it. I only want to use something like e.Index.
I know that the index is not a member in e, but I don't want to use listview item check event due to loops.
how I can find the index for the listview items without using for each integer as only using e.index?
